Photosynthesis : Photosynthesis is an enzyme regulated anabolic process of manufacture of organic compounds inside the chlorophyll containing cells from carbon dioxide and water with the help of sunlight as a source of energy. The ratio of the volume of C02 evolved to the volume of 02 consumed in respiration is called Respiratory Quotient (RQ) or respiratory ratio. Respiration in Plants Class 11 Biology Chapter 14 Notes All living organisms require a continuous supply of energy for their survival. Hello Guys, Download Respiration in plants - Class 11 Biology Hindi notes in PDF. However, they don’t breathe as most animals do, as plants do not have organs dedicated to the process of gaseous exchange. During oxidation within a cell, the energy is released in a series of slow stepwise reactions controlled by enzymes and trapped as chemical energy in the form of ATP. This process of respiration is essentially the process of photosynthesis but in reverse. Glycolysis. Here, both NADH + H+ molecules are used in reduction of acetaldehyde hence, net ATP production is only 2. For complete oxidation of glucose to C02 and H20, organisms follow Krebs’ cycle, as well as electron transport chain. Cellular respiration involves breakdown of the C-C bonds of compounds of food.

pyruvate leaving 3 molecules of CO, passing electrons eliminated as part of hydrogen atoms to molecular oxygen with a parallel synthesis of ATP, Where aerobic respiration is the complete degradation of carbon dioxide and water, fermentation results in the partial  breakdown of glucose only, Aerobic conditions lead to the formation of several molecules of ATP whereas the net gain of only two molecules of ATP is observed for each molecule of glucose  degraded to pyruvic acid in the process of fermentation.
